Mr. Burns sits in his office awaiting the union leader, who has not been seen since he promised to clean up the union, so that they can discuss the proposed union contract. While perusing the contract, Mr. Burns becomes disgusted with the union demands and reminisces about simpler times. Mr. Burns then decides to take on the union and revoke their dental plan.
Meanwhile, at Painless Dentistry, the Simpson children are getting their teeth checked. It is discovered Lisa needs braces. When Marge informs Homer, he tells her not to worry about the cost, as the union had won a dental plan during the strike of '88. Later, at a meeting of the local chapter of International Brotherhood of Jazz Dancers, Pastry Chefs and Nuclear Technicians, Carl announces that the newest contract requires the union to give up their dental plan in exchange for a free keg of beer for their meeting. Homer slowly comprehends that giving up their dental plan would require him to pay for Lisa's braces and jumps into action, reminding everyone how their dental plan has helped them all, and how the new contract is an insult. Carl proposes Homer be the new union president and he is promptly elected by a nearly unanimous vote.
Mr. Burns watches Homer on his hidden cameras and is impressed, asking Smithers "who is that firebrand?" He further confuses Homer's pathetic attempt to remove a sugar daddy stuck on his back with a work-out routine. Burns invites Homer to his office to try to reach an agreement but Mr. Burns' sly innuendos are misconstrued by Homer as sexual advances. Homer quickly gets to his feet, saying he does not go for those "back door shenanigans" and promptly leaves.
Since the dental plan has not yet been reclaimed, Lisa is given exceptionally primitive braces, leading her to call herself a "monster". Meanwhile, Mr. Burns sends hired goons to the Simpson's house in order to take Homer back to Burns' Manor to negotiate. Before they have a chance to talk, Homer is struck by the urgent need to use the rest room. He asks Mr. Burns where the rest room is and immediately leaves, causing Burns to think that Homer is unwilling to even hear him out. Homer finally becomes fed up with Mr. Burns and calls a meeting where the union immediately vote to strike.
Mr. Burns is undeterred by the strike and tries several methods of breaking it up, such as bringing in '30s era strikebreakers and getting loyal robot workers. On an edition of Kent Brockman's talk show "Smartline", Mr. Burns is allowed an opening tirade and he threatens dire events. Fifteen minutes later, Mr. Burns and Smithers march to a secret room in the Power Plant and turn off the power for the whole town. The strikers do not lose hope and begin to sing. Burns, confident he has broken the union's spirit, steps out on his balcony to hear their reaction but is disarmed by their unity and optimism. Mr. Burns finally calls a meeting with Homer to concede to their demands on one condition: that Homer must resign as union president. Homer celebrates, causing Mr. Burns to finally realize that Homer is not a brilliant tactician.
With the Simpson family insured again, Lisa gets her perfect, new braces and she, the Simpson family, and the dentist gather and laugh as the episode comes to a close. - source Wikipedia.
A character in the 90's television series Beavis and Butt-head, Butt-head wears dental braces and has squinty eyes. His top gums are often exposed due to a small upper lip, and he speaks nasally with a deep voice and a slight lisp, repeatedly punctuating his speech with "uhh…."
Calmer, cockier, and marginally more intelligent than Beavis, Butt-head is oblivious of subtleties, but is usually 100% confident in everything he says and does — no matter how ridiculous or frivolous it is. The designated "leader" of the duo, he derives pleasure from being regularly abusive to Beavis. In most episodes, when there is a problem, he says, "This sucks!" and then Beavis tells him what the problem really is.
Creator, Mike Judge got the idea for the name Butt-head from two kids called "Iron Butt" and "Butt-head" whom he knew during his college years.
The actor Tom Cruise apparently wore ceramic braces when he decided to fix what was described as a minor bite problem. Ceramic braces are made of a composite material that is generally very strong and stain resistant. Many adults considering braces prefer ceramic braces to the more traditional metal braces because they very closely match the natural tooth color and are nearly invisible.
